摘要： An electrode that is used for discharge surface treatment in which, with a compact molded from metal powders or a compact obtained by heating the molded compact as an electrode, pulsed electric discharge is generated between the electrode and a workpiece to form a film of an electrode material, or a film of substance that reacts with the electrode material on a surface of the workpiece by discharge energy. The electrode contains 90 weight percent or more of one of Zn powders, Sn powders, and Ni powders. By using such an electrode for discharge surface treatment, a Zn, Sn, or Ni film less likely to separate from the surface of the workpiece can be formed, and the film can be a phosphide or sulfide reaction film in lubricant containing phosphorus or sulfur.

摘要： An electrode for an electrical-discharge surface-treatment method is molded with a metallic powder or a metallic compound powder having an average grain diameter of 6 micrometers to 10 micrometers. A coat on a surface of a workpiece is formed with a material constituting the electrode or a substance that is generated by a reaction of the material due to a pulse-like electrical discharge. The coat is built up with a material containing metal as a main constituent under conditions of a width of a current pulse for the pulse-like electrical discharge in a range of 50 microseconds to 500 microseconds and a peak of the current pulse equal to or less than 30 amperes.

摘要： To form a thick coating by a discharge surface treatment, a voltage between an electrode and a workpiece during a discharge is detected, and it is determined that a discharge surface treatment state is abnormal if it is detected that the voltage is reduced. With this arrangement, it is possible to accurately detect an unstable phenomenon in the discharge surface treatment, and take appropriate measures before a state of the coating and a state of the electrode are worsened due to the unstable phenomenon. By discriminating a stability of the discharge surface treatment, the coating and the electrode are prevented from being damaged.
